AEROPLANE Filed July 29, 1929 2 Sheets-Shet I Patented Apr. 15, 1930 HENRY PODOLSKY, OF SAN FRANCISCO, CALIFORNIA AEROPLANE Application filed July 29, 1929. Serial No. 381,868.

This invention relates to improvements in aeroplanes, and has for its object the provision of means for lifting the craft, as well as driving it ahead.

Another object is to provide an opening 1n the top coverlng of the wing and mounting a propeller over the opening so'that the air will be driven in at the top opening, and conveyed between the top and bottom coverings of the wings to an opening in the bottom covering on each side and spaced from the top opening. From these openings the air is driven around the bodies of the side propellers and onto the underside of the wing acting to aid in lifting the plane.

Another object is to provide a propeller in front and a propeller in the rear on each side of the fuselage.

Another object of the invention is to provide projecting front and back ailerons for the control of the craft.

Other objects of the invention will be apparent as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout the several figures of the drawings, and of which there may be modifi cations.

, Figure 1 is a side elevation of the aeroplane showing the wing in section, and 1 Figure 2 is a front elevation showing the aeroplane partly in section.

The numeral 1 indicates the fuselage which is provided with suitable windows 2, and doors 3. No control levers are shown as these may be of well known construction.

The wing is represented by the numeral 4;, and is of the usual construction of girders 5 and 6 and ribs 7, top 8, and bottom 9 covering surfaces.

On the advancing edge are pivotally mounted the vanes 10 and-11 for controlling the aeroplane in cooperation with the vanes 12 and 13.

. the aerofoils 14 and 15.

'27 indicates the wheels,

On the sides of the fuselage are mounted These are fixed and act as additional supporting surface. A rudder 16 is pivoted on the rear of the fuselage.

On each side of the fuselage are mounted the housings 17 and 18, and

at the front ends of these housings are the propellers 19 and 20, and engines 21 and 22, and on the rear ends of the housings are propellers 23 and 24;, and

engines 25 and 26.

Suitable landing gear is provided in which and 28 the frame which is fixed to the fuselage.

In the top covering of the wing is the opening 29, and the propeller above the opening is mounted 30 and engine 31.

Extending from near the edge of the opening 29 on each side through the openings 32 and 33 in the around the housings bottom cover of the wing down 17 and 18, but leaving a space therebetween are the deflectors 3 1 and 35, which deflect the air from the propeller around and up under the wing surface,

and builds up a density of and acts to lift the wing.

The engine is supported cross bars 37 and 38. Braces air thereunder,

on the legs 36 and 39 and 40 extend from the wings to the deflectors and are provi'ded with lateral braces 11 and 42 which serve to stiffen the structure.

and 44 prevent the air The ends 43 blowing out through the space around the housing.

In starting a flight the operation is as lows All the propellers folare started until a suiticient speed is attained to support the plane when the controls are operated to cause the plane to rise in the air.

The propeller drives it through 30 in pulling the air down the opening 29 into the interior of the wing and out through the openings 32 and 33 around the housings 17 and 18, and up against the bottom surface of the to tend to raise wing to build up air density the wing.

a propeller opening, an opening on each p opening in the bottom wall of said wing, air from a propeller mounted above said opening, means to deflect air from said propeller down through, and up under said wing, and means to drive said propellers.

0. An aeroplane comprising a hollow a fuselage fixed to said wing, a housing on each side of said fuselage, a propeller on each end of said housing, a central opening in the top 1 wall of said wing, a propeller mounted in said opening,

from sald central opening through said bottom openings, and around pointing upward adjacent means to drive said propellers singly or together.

4. An aeroplane comprising a hollow wing structure, a central opening in the top wall of said wing, a propeller mounted on said wing above said opening, openings in wall of said wing each of, and space from said central opening, deflectors adapted to defl from said propeller down through said wing, and up under the wing, and means to n aeroplane having a hollow wing, a fuselage fixed to said wing, pivoted vanes projecting forward from the advancing edge of said wing, pivoted vanes projecting backward from the following edge of said wing, a housing on each side of said fuselage, and
